It is the object of the invention to providev an exceptionally simpleand inexpensive burner construction, yet onewhich will be highly ,oefficient, will operate to equal advantage inV the consumption ofnatural or artificial gas, and will function properly without allowingescape of gas whether the gas pressure be low or high.

With the foregoing in view, the invention resides in the novel subjectmatter hereinafter described and claimed, description being accomplishedby reference to the accompanyindrawing. Y Y l ...o ig. 1 is a transversesectional view through a gas heater showing the burner installed.

Fig. 2 is a perspective view of the burner.

Fig. 3 is a vertical longitudinal section partly in elevation, asindicated by line 3-3 of Fig. l.

A construction is disclosed which has proven to be of great advantagefrom all standpoints, and while such construction will be hereinspecifically explained, it is to be understood that minor variations maybe made.

The burner embodiesia horizontally elongated shell 5 preferably ofquarter-cylindrical form, the curved upper portion of said shell beingprovided with gas discharge perforations 6 and 7, while the bottomofsaidshell is formed with two longitudinally spaced openings 8. The upperends Vof two vertical pipe nipples 9 pass through the openings 8 and arethreaded into two Ts 10 withi in the shell 5, said Ts opening towardopposite ends of said shell and constituting gas distributing heads.Nuts 11 are threaded upon the nipples 9 and coact with the lower ends ofthe Ts 10 in securely .fastening Vsaid nipples in the openings 8.Threaded upon the lower ends of the nipples 9, are two verticallydisposed air and gas mixers 12 whose lower ends are provided with elbows13. The upper ends of these elbows embody nozzles 14 forverticallydischarging gas, and the lower ends ofsaid elbows are directedhorizontally inward towardzeach other. Two horizontal pipenipplesfl'`are threaded into the lower f ends' of theelbows 13 and are disposed inaxial "isili alinement with eachother, the inner endsy of Vthese nipples15 being threaded into the head 1-6 of a T 16.,` vThe shank .of the T isdisposed l upwardly, and the reduced down-turnedend of a service L17, isthreaded into Vsaid shank'. o

Ahorizontal' gas ,pipe y18, transverse tothe nipples 15, is threadedinto` the service L17@ u .The construction described, provides such a`tortuous coursev for the incoming gas,.that

its `Veloci-ty is checkedwhen said kgasfiswat 165, .unusually highpressure. Thus, lthe 4'gas-is prevented from blowing-"from th-eperforations and` 7 with such force'as to prevent proper combustion.'V`Then too, whenthe gas is at unusuallyflow,- pressure, for instance,fthe'f )pressure of ,natural'gas during cold weather, .nonei of this gaszc'an'escape unburned, due to *the vertical positionsof the mixers 12.`The Vnatural tendency kof the gas kto ascendV l asfit .leaves thenozzles 14, prevents it from es capl'1:5

ing through the air intake openings of 'the mixers12,whereas if thesemixers were hori- .zontally`p.osit ioned, somelof theV gas Ewouldescapethrough saidopenings, [A furtherv ad- 1 vantage of the improvedconstruction, isfthat so, it,A operates, toequal advantage with eitherartificial or natural gas, whereas, prior burn-v ers have necessitatedspecialdetails for-burning'natural gas and 'other specialk detailsv forfthe combstioncof, artificial gas.4 y Whether isa .the gas beV naturalor artificial, the improved Vburner Voperates atvamuch higher state ofeiliciency than J any other burner with which I amrfalmiliar.

Attention isf'invited to the fact thatjtheso s burner is ofquarter-cylindrical form. I f;v it

were acomplete cylinder,it would be so large that in burningbr tryingto'` burnfafsmall amount of gas for'heating a smallroom,

proper combustion could not be produced, `for 95 s the quantity of gasfed into the burner would be too small with regard to the quantityof'air contained in said burner. p The shape of the burner provides itwith a large face vover which to distribute and burn the gas insingleloo f jets of llame. This face of the burner presents as much areafor burning gas as there vwould be in a conventional five inchcylindrical burner, so that large consumption of gas for hea-ting largerooms can be readily eected, regardless of the fact thatl the burn-er issufficiently small to consume small quantities of gas forheating smallrooms.V

Another advantage of the shape of the burner is that, if it werecylindrical, it could notbe placed as tight against the fire wall intheheater as if it were not of cylindrical form. v ,f j Y I claim 1. A gasburner comprising ahorizontally elongated shell provided with aperforated V upper portion, saidfshell having two longitudinally spacedopenings .in-its bottom, two vertical pipe nipples passing throughv andsecured in said openings respectively, gas distributing heads on saidnipples within said shell and. opening toward opposite ends of thelatter, twoY vertical 'gas and air mixers connected with the lower endsof said nipples respectively, kthe lower ends of saidvr mixers beingprovided with elbows whose lower ends project inwardly'toward eachother, two hori- V zontal. pipe nipples connectedwith said'lower ends ofsaid elbows and projecting inwardly toward each other, a. T with whosehead the .inner ends of said horizontal nipples are connected, the:shank of said T being disposed vertically, a service L connected withsaid vshank of said T, and al horizontal gaslpipe lconnected with saidservice L. i- Y 2, A gas burner comprising a horizontally elongated'shell provided with a perforated upper portion, said shellfhaving twolongii tudinally spaced'openings in its bottom, two -vertical pipenipples passing through and 'secured in said openings respectively, gasdis- 'tributing heads on said nipples within said vshell and openingtoward opposite ends of vthe latter, two vertical gas and airmixers-con- 'nectedwith the lower ends of said nipples respectively, thelower ends of'saidf mixers i being provided with elbows whose lower endsproj-ect inwardly toward each other, two horij zontal pipe nipplesconnected with said lower ends of said elbows and projecting inwardlytoward each other, a T'with whose head the inner ends of said'horizontalnipples are cony'nected,` the shank` of said T projecting up- Ywardly,av service L havingits reduced end turned downwardly and connectedwith'said shank of said T, and a horizontal gas pipe z connected withsaid servicey L.

In-testimony whereof I'aflix' my signature.
